Young men flocked to join up and many never came home.
We’ve been trawling our archives at the Worksop Guardian to tell the stories of some of the brave men and boys from the town who lost their lives in the four-year conflict.
And the one who made it out alive and went on to join Nottinghamshire Police.
Take a scroll through to learn about their lives and tragic deaths.
